How we scored it

Structure not given in CosIng; silicone quaternary class. Siloxane backbone 0 by this site's convention; no natural fragment can be identified, so 0 / total = 0.00 (provisional).
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Quaternary ammonium-modified silicone made by organic synthesis from petrochemical and silicon feedstocks. Any natural alkyl groups (for example coconut-derived) would raise the value if the structure were confirmed.

In plain English

A silicone modified with quaternary ammonium groups, used in hair products to condition and reduce static. It is made in a factory from silicon and petrochemical raw materials. Its exact composition is not published in the regulatory database.
